Dogtra 7100H

[tuffloud1]

Does anyone have the 7100H, if so how do you like the vibration on the transmitter assuring you that the stimulation has been successfully transmitted? I read a review stating that the vibration in the transmitter will go vibrate no matter what, whether the collar is on or off. This would indicate that there is no assurance that stimulation was successful, it just indicates that the button on the transmitter was pressed.

Anyone know anything about this model? It appears to be the same as the 1900NCP, except with the transmitter vibration feature. I would like to get the 7100H instead, but I would like to know if it vibrates only with the button pressed or if it vibrates when the signal has been successfully sent.
